V 2 Claims.

This invention relates to a device for cutting off a sole which has been ripped by its forepart from a shoe, whereby the cutting action is done in situ. A primary object of the invention is to provide a structure which will cut off the sole, normally a sole which has been worn and needs replacing such as is commonly done in half-soling, whereby the cut through the worn sole will be absolutely uniform laterally across the sole so as to make the out on a bevel in a common plane. Heretofore all such cutting operations have been done by hand in the shoe repair shop with the result that the cut is not uniform entirely across the sole since there is nothing to guide the knife when operated by hand, and the result has been that in applying the new tap or half-sole, the lapping of that new tap over the cut results in an uneven appearance, and in fact leaves a terminal marginal edge which is easily lifted after usage following the completion of the repair.

A further primary object of the invention is to provide a structure which will be suitable for cutting off the worn sole regardless of its thickness, such for example as the thin sole of a womans shoe or the heaviercsole of a mans shoe, and still obtain a uniform, planar surface of the cut.

Further important objects of the invention are to be found in that the cutting line across the sole is visible to the operator at all times; the adjustment required for varying thicknesses of soles is had by simply turning a hand operated lever; ample room is provided for the shoe to be operated on so as to get the cut as far back on the base or rear end of the sole as may be desirable immediately ahead of the heel; ease of operation of the device; a relatively low cost of production of the device; and extreme durability of the structure embodying the invention.

These and many other objects and advantages of the invention will become apparent to those versed in the art in the following description of one particular form of the invention as illustrated in the accompanying drawings, in which Fig. 1 is a view in front elevation of a structure embodying the invention;

Fig. 2, a view in side elevation;

Fig. 3, a detail on an enlarged scale in vertical transverse section on the line 33 in Fig. 2;

Fig. 4, a view in top plan; Fig. 5, a view in horizontal transverse section on the line 5-5 in Fig. 1; and N Fig. 6, a view in vertical longitudinal section on the line 6-4; in Fig. 1 with a shoe in operative position.

Referring to the drawings, in which like characters of reference indicate like parts throughout the several views, a base "I0 is provided to carry thereon in a fixed manner an upwardly extending frame ll, herein shown as being generally U-shaped. This shape is provided by means of the two spaced apart arms 12 and I3 which extend from the lower portion of the frame II. There is fixed rigidly to the upper end of these arms [2 and 13 the side names I l and i5 respectively. The upper rear end portions of these side frames l4 and [5 are preferably interconnected by means of a spacing b'ar l6.

Forwardly of the frame ll, there is positioned in a loose manner o'nthe top side of the base ill, a cam sleeve ll cylindrical nature. This cam sleeve H has an upper surface l8 planar in nature, and inclined from the horizontal. A vertically disposed bore 19 extends through the base l0 and in a continuous manner upwardly and centrally through the cam sleeve ll to open from the top surface l8 thereof. I

A post 20 is carried Within the bore I9 with a sliding fit and has fixed to its upper end the base 2| of a fork 22 which is provided with the spaced apartupw'ardly extending arms '23 and 24.

The base 2| is generany planar in respect to its under 'fsu'rfac 25. From this surfae 25, there extends downwardly on one side of the post 233, a tooth 26 which normally is in sliding contact with the inclined surface 18 of the cam sleeve l| On the upper ends of the arms 23 and 24 there is provided to extend therefrom restat tively the adjustable studs 21 and 28, securedin adjustment by any suitable means, such as by the look nuts 29 and 30. On the upper ends of these studs 2! and 28 there rests the rear end portions of a bed 3|.

This bed 3| is rockably supported by endtrunnions 32 and 33 rockably extending in longi tudinal alignment throughthe extreme forward and lower end portions of theside frames l4 and 15. The bed 3| is yieldingly urged down wardly into contact with these studs 21 and 28 by any suitable means, such as by a spring 34, Fig. 3, interposed between the frame thereabove and the bed 3| therebelow.

A lever 35 is fixed to the boss or sleeve l1, Figs. 2 and 5, to, extend rearwardly through a window 36 provided between the base Ill and the frame I I. By rocking this lever 35 horizontally, the cam sleeve I! may be rotated about its axis, as defined by the post 20 extending therethrough so that the tooth 2B in contact with the surface l8 may be elevated or lowered in accordance with the degree of turning of the member Thus the bed 3| may be raised and lowered depending upon the direction of rocking of the lever 35. I A cutting knife 31 is provided to be reciprocated horizontally between the frames l4 and I5. In the form herein shown, the opposite ends of the knife 3l-ldesign'ated by the numerals 3B and 39 are slidingly carried in fore and aft directions within the horizontally disposed slots 40 and 4| respectively provided in the opposing faces of the frames M and I5. These slots 4|] and 4| are located in relation to the bed 3| so that the forward edge 42 of the knife 31 will be guided to just clear the forward end of the bed 3| when rocked downwardly to have its top surface inclined from the horizontal. r v

The knife 31 has extending upwardly thereof and within the space between the frames l4 and in relatively close proximity thereto respectively the blocks 43 and 44, the top faces of which provide racks 45 and 46 respectively, The racks 45 and 46 are so positioned as to pass with clearance under the tie bar l6. As indicated,.Fig. 4, these blocks 43 and 44 extend downwardly a distance to carry the feet 4'! and 48 respectively to enter with a sliding fit the slots 40 and 4| behind the knife 31. In the form herein shown, these blocks 43 and 44 are formed integrally with the knife 31. 7

An operating shaft 49 is revolubly carried by the side frames 4 and I to have fixed thereon the pinions 50 and 5| meshing respectively with the racks 45 and 46. This shaft 49 extends horizontally and outwardly from the side frame M a sufiicient distance to have mounted thereon an operating crank 52. Thus by turning the crank 52, the knife 31 may be reciprocated horizontally to approach and be withdrawn from the bed 3|. The upper surface of the bed 3| is provided with knurls or serrations 53in order to preventslippage during thecutting operation.

To operate the device, a shoe 54 has the'sole' 55' ripped therefrom back a distance beyond the line at which it is desirable to be cutoff in the repair operation. The shoe54 is inserted by the toe end betweenthe fork arms Hand 24 in an upside down relation to have the sole 55 extend over the'bed 3|, and the shoe 54 is pushed for-- wardly in relation to the knife 31 which is then the zone A over the bed 3| so that the bed 3| will support the sole 55 while the edge portion 42 passes therethrough. Then the. crank 52 is turned to advance the knife 31 toward the zone A so that the cut will be made across the line designated by the numeral 56. Following-this cutting operation, the crank handle 52 is then turned to retract the-knife 3! from over the bed 3|, and the shoe 54 may be withdrawn from the device and the new tap (not shown) placed on the shoe and attached thereto all in the usual and well known manner. By reason of forming the cut across the sole 55 to come on some such a line or plane as indicated by the numeral 55, a perfect bond may be made'by the predetermined bevel provided on the tap with this surface'56 4 whereby to all intent and purpose the edge of the bond will not be apparent after the repair has been made.

While we have herein shown and described our invention in the one particular-dorm, it is obvious that structural changes }may.be employed without departing fronf'the spirit of the invention, and we therefore do not desire to be limited shoe soles for replacement purposes comprising a relatively vertically rockable and horizontally disposed knife bed; a cutting off knife; side frames guiding said knife in a horizontal direction toward and away from said bed; means spaced above and to the sides of said knife for reciprocating it; and means supporting said bed and said knife to provide clearance thereunder of a shoe in upside down relation with the sole thereof passed under said knife and over said bed; said knife bed being rockably supported by its ends adjacent its side farthest removed from said knife; and means for rocking said bed, comprising a forked member having upper horizontally spaced arms presented under rear end portions of the bed, a post extending downwardly from the forked member, a base having a bore receivme said post. a cam sleeve circumferentially revoluble about said post between the base and the forked member, and a cam follower on said forked member.
